The scientific tourist #203 — Swiftcurrent lake

This week’s photo comes to you from Swiftcurrent lake — a beautiful little lake in the Many Glacier region of Glacier National Park in Montana:

Swiftcurrent Lake

The mountains in the background get their shape from the same force that lent its name to this part of the park — the mountains are what’s left after the glaciers of the last ice age retreated. Swiftcurrent lake was created from the combination of glacial-driven erosion (carving its basin), retreat deposition (leaving a moraine to impound water), and melting (to fill the lake).

Sadly, though, only 25 active glaciers remain of the 150 or so that were here 150 years ago — and they’ll be gone in another decade, if current warming trends continue.
